| 20100124677 | DIRECT OXIDATION FUEL CELL SYSTEM WITH UNIFORM VAPOR DELIVERY OF FUEL - A fuel cell system which includes a fuel distribution structure that uniformly distributes vaporizing fuel to a fuel cell is provided. As the fuel travels in a flow field channel in the fuel distribution structure, it is substantially converted to a vapor by the heat of the fuel cell operation in such a manner that the resulting vapor pressure works to substantially uniformly distribute fuel evenly outwardly across substantially the entire active area of the anode aspect of one or more membrane electrode assemblies in the system, and whereby localized, uneven “hot spots” of fuel at the anode aspects are substantially prevented. A pair of enthalpy exchanger and heat spreader assemblies include a cathode current collector element that also has a heat spreader plate that collects and redirects heat in the fuel cell system, the assembly acting to manage the heat, temperature and condensation in the fuel cell system. | 05-20-2010 |

| 20100108534 | ELECTROCHEMICAL ACTUATOR - A valve system includes a gas generator coupled to a first chamber and a passage for conveying a flow of fluid therethrough. The first chamber is configured to hold a gas generated by the gas generator. The chamber includes a diaphragm deformable in response to an increase in an amount of the gas in the first chamber received by the gas generator. A deformation of the diaphragm in response to the increase in the amount of the gas in the first chamber inhibits flow of the fluid through the passage. | 05-06-2010 |
| 20100108536 | ELECTROCHEMICAL ACTUATOR - An electrochemical actuator system includes a membrane electrode assembly coupled to a source of electrical energy. The membrane electrode assembly includes a proton-exchange membrane disposed between a first electrode and a second electrode. A first chamber is located on a first side of the membrane electrode assembly and is configured to hold a gas generated by applying electrical energy to the first electrode of the membrane electrode assembly. The membrane electrode assembly and the first chamber are sealed to inhibit fluid communication with the surrounding ambient environment. The chamber includes a diaphragm deformable in response to a change in an amount of the gas in the first chamber. A deformation of the diaphragm in response to the change in the amount of the gas in the first chamber causes a movement of an actuating member coupled to the diaphragm. | 05-06-2010 |
| 20100112381 | ELECTROCHEMICAL ACTUATOR - A heat switch system includes a first surface thermally coupled to at least a portion of an associated component requiring temperature control. A second surface is spaced by a gap relative to the first surface. A gas generator is coupled to a first chamber configured to hold a gas generated by the gas generator. The first chamber includes a diaphragm configured to be deformed in response to an increase in an amount of the gas in the first chamber. A deformation of the chamber in response to the increase in the amount of the gas in the first chamber causes movement of the first surface and/or the second surface such that the first surface and the second surface move toward each other to reduce the gap and heat is transferred from the first surface to the second surface. | 05-06-2010 |

| 20100296928 | Wind turbine accelerator panels and method of making same - A vertically sectioned cylindrical accelerator for mounting pairs of wind turbines respectively on opposite sides thereof has a covering of twin-sheet thermoformed plastic panels which are smooth on the outside but carry a multiplicity of small cone-shaped projections on their interior surface. The panels are mounted on a structural member by a single central bolt for free expansion and contraction with variation in ambient temperature. The panels are manufactured in a twin-sheet thermoforming operation wherein one sheet is maintained with a smooth surface and the second sheet is provided with the cone-shaped projections, the two sheets being fused together to form an integral panel of lightweight and high strength characteristics. | 11-25-2010 |
| 20110076146 | Wind turbine electrical generating system with combined structural support members and straightening vanes - A wind turbine electrical-generating system with air-directing vanes in the forms of sheaths over structural members crossing the sir discharge opening of the wind turbines. The turbines also have associated shroud assemblies which support the structural members and which cooperate with the vanes to provide superior performance. | 03-31-2011 |

| 20100323117 | SYMMETRICAL MULTI-PORT POWDER INJECTION RING - Powder injection apparatus, plasma gun, and method of use. Powder injection apparatus includes a shroud attachable to an outlet nozzle of a thermal spray apparatus and a substantially smooth and continuous inner wall defining a bowl through which a plume of the thermal spray apparatus travels. At least one port in the inner wall is structured and arranged to receive a powder injection nozzle that injects powder into the plume. | 12-23-2010 |

| 20100168522 | SURGICAL ACCESS ASSEMBLY - A surgical access assembly configured and dimensioned for positioning within an intercostal space defined between a patient's adjacent ribs to facilitate passage of a surgical instrument into an internal work site. The surgical access assembly includes a body portion that may be either partially or wholly formed from a resilient material such that the surgical access assembly is resiliently deformable to facilitate conformity with the intercostal space in order to minimize the application of force to the patient's tissue upon insertion and removal of the access assembly and manipulation of the surgical instrument. | 07-01-2010 |

| 20090219162 | Speaker Circuit Resident Notification Appliances - Both notification appliances and speakers usable to broadcast verbal messages into a region can be coupled to common signal and power providing communication lines. Composite output modules can include speakers, horns, and strobe lights, all without limitation, which can be independently driven and controlled from a common pair of lines. | 09-03-2009 |
| 20090296897 | System and Method of Telephone Input for Alarm Events - An interface between a telephone-type communications system and a regional ambient condition monitoring system receives incoming verbal status information relative to the region. That information can be transferred to the monitoring system. Verbal messages can be fed back to the communications systems to provide information as to responding to conditions in the region being monitored. | 12-03-2009 |

| 20100185560 | System, Method, and Computer Program Product for Allocating Assets Among a Plurality of Investments to Guarantee a Predetermined Value at the End of a Predetermined Period - A system, method, and computer program product for allocating assets among a plurality of investments to guarantee a predetermined value at the end of a predetermined time period. A computer program controls the allocation of assets in the investment vehicle, which allows the investor to initially invest one hundred percent of the initial deposit in non-secure, high risk investments. At the end of the each trading day, the computer program determines if assets should be reallocated from the non-secure investments to the secure investments, from the secure investments to the non-secure investments, or if no reallocation is necessary. | 07-22-2010 |
